Description
Despite their simplicity, O(N) scalar field theories, or O(N) models for short, allow for the investigation of several interesting phenomena such as asymptotic freedom and spontaneous symmetry breaking. On the lattice, O(N) models can be represented in terms of integer-valued flux variables, which allow for efficient Monte Carlo (MC) simulations both at zero and non-zero densities with a worm algorithm.
As a characteristic property of all quantum systems, entanglement provides a novel way to study different QFT phenomena. In recent years, significant progress has been made in lattice computations of entanglement measures such as entanglement entropy (EE).
In my poster, I will present our approach in incorporating evaluations of EE using the replica trick into MC simulations of O(N) models at finite density with the worm algorithm and showcase our results on how the derivative of EE w.r.t. the width of the entanglement region changes as a function of both the density and the width itself.
